Abstract
Description
Technical Field
[0001] The invention relates to an electrical connection system, in particular a system for automotive applications, having at least one female terminal partially arranged in an outer housing, the female terminal being configured to engage with a corresponding male terminal. The invention also relates to a method for assembling a corresponding electrical connection system. Background Art
[0002] In recent years, the automotive industry is facing a shift towards electric vehicles, which are becoming increasingly important and popular with consumers. This shift, in turn, is accompanied by a growing demand for electrical components. This also increases the demand for electrical connection systems, which are used to connect one electrical component to another. On the one hand, such electrical connections can be used to transfer power to electrical consumers. On the other hand, such electrical connections facilitate data distribution in the car.
[0003] These types of electrical connection systems include female connectors that include an outer housing and female terminals that can be engaged with corresponding male terminals for providing electrical energy. The female terminals are typically bent, for example, by about 90°, to allow flexible arrangement and orientation of the wires.
[0004] The current state of such electrical connection systems used in particular in the automotive industry reveals several disadvantages.
[0005] For example, it is difficult to keep the female terminal in a substantially centered position in the female connector housing. In turn, the mating with the male terminal is also adversely affected. In particular, the female terminal may deviate from the center, which is not conducive to mating. In addition, the male terminal may damage the female terminal during mating, which may have an adverse effect on the electrical connection. In addition, the female terminals are usually non-fixed, which makes them easy to move, so that they may contact the inner surface of the housing. This may lead to damage to the female terminal. In addition, if overmold is not applied and / or during overmolding, the lack of any fixation can lead to a large swing of the female terminal, especially in the assembled state.
[0006] Overall, some electrical connection systems are therefore unsuitable for use in the automotive industry, which can lead to an increase in waste material. This, in turn, significantly increases costs for manufacturers.
[0007] In this context, there is a need to improve the existing known electrical connection systems because the current situation cannot meet the needs of manufacturers.
[0008] It is therefore an object of the present invention to overcome some or all of the disadvantages of the prior art. In particular, it is an object of the present invention to provide an electrical connection system that allows easy assembly with a strong, stable and predetermined arrangement. In addition, the mating with male terminals should be simplified. It is an overall goal to reduce costs and increase flexibility by providing an improved electrical connection system. Summary of the invention
[0009] The above objects are at least partially achieved by the subject matter of the independent claims. Preferred embodiments are the subject matter of the dependent claims, and a person skilled in the art can find hints of other suitable aspects of the invention through the overall disclosure of this application.
[0010] Aspects of the present invention relate to an electrical connection system for automotive applications, the system comprising: an outer shell defining a mating direction; at least one female terminal comprising a first elongated portion oriented substantially parallel to the mating direction and at least partially received in a hollow portion of the shell, a second elongated portion oriented in a direction different from the mating direction, and a bent portion between the first and second elongated portions; wherein the first elongated portion has a receiving portion opposite to the bent portion for mating with a corresponding male terminal; wherein the bent portion has at least one supporting member for supporting the female terminal on a surface of the outer shell so as to substantially prevent movement of the female terminal in the shell.
[0011] In this way, the present disclosure provides an electrical connection system that has the advantage of being easy to assemble. The arrangement of the individual components of the electrical connection system, in particular the arrangement of the female terminals, is maintained in a predetermined manner. This facilitates the mating with the corresponding male terminals. Therefore, substantially no failure and / or damage occurs during mating. Therefore, the electrical connection system can be adopted in various application scenarios that require mating with male terminals. Since no special attention is required for mating, the overall flexibility of the application scenarios is increased. For example, an operator and / or a robot does not need to pay special attention to mating. Therefore, the costs associated with manufacturing and assembly are reduced.
[0012] Due to the support member, the female terminal is firmly maintained on the surface of the outer housing. This is particularly beneficial for the manufacturing steps of the electrical connection system, during which covers and / or overmoldings are applied. During such manufacturing steps, the solutions of the prior art are usually prone to swinging and / or moving the female terminal, which makes the precise positioning of the female terminal in the outer housing of the solutions of the prior art difficult. According to the electrical connection system proposed by the present invention, the support member has the advantage that any accidental movement of the female terminal is prevented. The female terminal is thus protected from accidental rearrangement, reorientation, displacement or the like.
[0013] In summary, the support member of the bent portion of the female terminal significantly facilitates assembly and improves the reliability of the electrical connection system. It can be understood that its applicability is also enhanced.
[0014] As used herein, any terminal may be understood as an electrical terminal that allows for an electrical connection.
[0015] The first elongated portion and the second elongated portion are understood to each have a shape having at least one dimension (size) greater than any of the other two dimensions. Thus, an elongation axis can be recognized, which defines the first portion and the second portion as the first elongated portion and the second elongated portion, respectively. The shapes of the first elongated portion and the second elongated portion may be different from each other.
[0016] The first elongated portion and the second elongated portion can be portions of any length of the female terminal, respectively. It can be understood that since the extensions of the first elongated portion and the second elongated portion can intersect at an intersection point or an intersection edge, the first elongated portion and the second elongated portion themselves do not have to abut against the curved portion between the two elongated portions. However, it is preferred when the first elongated portion and the second elongated portion each abut against the curved portion on its opposite side.
[0017] The second elongate portion is oriented in a direction different from the mating direction meaning that their elongate axes are not parallel to each other. Preferably, they are oriented so that an angle can be defined in the curved portion as described elsewhere herein. The first elongate portion, the second elongate portion and the curved portion may be arranged substantially in one plane, which plane is parallel to the mating direction.
[0018] The mating direction may be understood by those skilled in the art as a direction along which the male terminal and the female terminal move to provide a mated state. The unmating direction may be parallel to the mating direction but oriented in the opposite direction.
[0019] The hollow portion of the housing may be large enough to accommodate the first elongated portion. It may be larger to accommodate one or more additional elements, such as a shielding element as described elsewhere herein.
[0020] The bend can be understood as a portion surrounding the female terminal, wherein the different orientations of the first elongated portion and the second elongated portion become visually significant. This can be stated as follows: the first elongated portion and the second elongated portion can be implemented by metal strips, and the extension segments (extensions) of each of the first elongated portion and the second elongated portion can define an intersection point or an intersection edge. A portion surrounding the point or edge and the vicinity of the point or edge can be referred to as a bend. In this way, the bend can include a portion of the extension segment of the first elongated portion and / or a portion of the extension segment of the second elongated portion. In other words, the bend of the female terminal may not be limited to the point or edge in the mathematical sense where the extension segments of each of the first elongated portion and the second elongated portion intersect.
[0021] The receiving portion may be arranged substantially at one end of the female terminal.
[0022] The support member may be understood as a structural element, the intended purpose of which is to substantially prevent movement of the female terminal in the housing or the like. In particular, movement of the first elongated portion may be substantially prevented. A person skilled in the art will appreciate that the support member requires more than just an arbitrary portion, surface, etc., for example affecting the center of mass of the female terminal simply by its presence.
[0023] It is understood that the surface of the outer shell can face the second elongated portion. In one example, the surface can have a normal line, which is parallel to the mating direction.
[0024] The electrical connection system may include a plurality of female terminals. Preferably, two female terminals may be included by the electrical connection system. The two female terminals may be substantially identical.
[0025] It should be noted that when features, aspects, and / or embodiments are described herein by the term "substantially," manufacturing tolerances must generally be taken into account. In this manner, there may be slight deviations during any type of manufacturing, assembly, or the like. In addition, there may be manufacturing tolerances, aging effects, or other minor defects or the like. These are all encompassed by the term "substantially."
[0026] In a preferred embodiment of the electrical connection system, the at least one support member is arranged such that a free edge of the support member at least partially contacts a surface of the outer housing.
[0027] The free edge at least partially contacting the surface has the advantage that the female terminal is supported to a greater extent.In addition to or instead of the surface facing the entire edge of the outer shell, the free edge of the support member may contact the surface.
[0028] In a preferred embodiment of the electrical connection system, the at least one supporting member is bent in the mating direction and extends from the second elongated portion such that the free edge substantially abuts the surface along its length in the direction of the second elongated portion.
[0029] This has the advantage that the support effect is enhanced, which in turn improves the fit.
[0030] The direction of the second elongated portion may be understood by those skilled in the art as the elongated direction of the second portion.
[0031] In a preferred embodiment of the electrical connection system, the at least one supporting member has the shape of a wing.
[0032] The wing has the advantage that it is a highly acceptable structural element that can be easily implemented and handled during manufacturing. The wing enhances the supporting effect of the supporting member.
[0033] In a preferred embodiment of the electrical connection system, the at least one supporting member is integrally formed as a single piece with the female terminal, wherein the female terminal and the at least one supporting member are preferably made from a stamped and bent metal sheet.
[0034] Thus, the manufacturing process can be improved. The one-piece formation reduces the number of multiple separate parts required. Being made from stamped and bent sheet metal means that the female terminal may have gone through a stamping and bending process. A person skilled in the art will readily recognize the difference in this manufacturing process compared to providing separate parts, since separate parts require attachment means. The preferred embodiments described herein have the advantage that the support member itself is a rigid and strong structure, without the need for any attachment means.
[0035] In a preferred embodiment of the electrical connection system, a surface of the housing is provided with at least one corresponding recess in order to at least partially accommodate the at least one support member.
[0036] This has the advantage that it enhances the fixing and maintaining of the female terminal in the correct position. The recess may have a shape similar to a portion of the support member. In particular, the recess may have a shape similar to the free edge of the support member, as described elsewhere herein.
[0037] In a preferred embodiment of the electrical connection system, at least one supporting member includes a slit on an edge facing the second extension portion, which extends along the extension direction of the second extension portion, wherein the slit preferably starts near the intersection of the first extension portion and the second extension portion and extends in a direction away from the intersection along the second extension portion, wherein the slit preferably extends in the direction along the second extension portion by at least 5%, preferably at least 10%, preferably at least 20%, preferably at least 30% of the length of the supporting member, and / or extends at most 90%, preferably at most 80%, preferably at most 70%, preferably at most 60%, preferably at most 50%, preferably at most 40% of the length of the supporting member.
[0038] The advantage of the slit is that the manufacture and / or arrangement of the female terminal is improved. For example, the slit helps to make it easier to bend the support member. This makes it easier to bend the support member so that it abuts the surface of the outer shell with substantially its entire free edge. In this way, the abutment of the support member with the surface can be adjusted more easily.
[0039] On the one hand, the slit should not extend over such a length that the stability of the support member may be compromised. On the other hand, the slit should extend to a sufficient length to facilitate easier bending during manufacture and / or assembly. According to the values specified here, an optimal balance has been found.
[0040] In a preferred embodiment of the electrical connection system, the first elongated portion intersects the second elongated portion in a bend having a bend radius between 0.05 mm and 0.8 mm, preferably between 0.1 mm and 0.6 mm, preferably between 0.2 mm and 0.4 mm.
[0041] A smaller bend radius helps the support member have more space over the bend. However, the bend radius should not be too small because this will increase mechanical stress in the female terminal, which may be detrimental to electrical transmission. The values specified here provide the best compromise between these conflicting requirements.
[0042] In a preferred embodiment of the electrical connection system, at least one supporting member has a width in a direction perpendicular to the second extension portion toward the surface of at least 0.2 mm, preferably at least 0.4 mm, preferably at least 0.6 mm, preferably at least 0.8 mm, preferably at least 1 mm, and / or at most 4 mm, preferably at most 2 mm, preferably at most 1.6 mm, preferably at most 1.4 mm, preferably at most 1.2 mm, preferably at most 1 mm.
[0043] This ensures that an optimal width of the support member is achieved. On the one hand, the width should not be too large, as this has an adverse effect on the waste of material. In addition, a larger width may bring the possibility of instability of the female terminal. On the other hand, the width should not be too small, as this would compromise the setting of maintaining a certain distance, such as maintaining the distance from the receiving part of the first extension to the housing opening, as described elsewhere in this article. According to the values specified here, an optimal balance is found.
[0044] Additionally or alternatively, the width of the at least one support member may be measured in a direction along the mating direction.Preferably, the mating direction is substantially perpendicular to the second elongate portion of the female terminal.
[0045] In a preferred embodiment of the electrical connection system, at least one supporting member has a length in a direction along the second extension portion of at least 0.4 mm, preferably at least 0.6 mm, preferably at least 0.8 mm, preferably at least 1 mm, preferably at least 1.5 mm, and / or at most 4 mm, preferably at most 3 mm, preferably at most 2 mm, preferably at most 1.8 mm, preferably at most 1.5 mm.
[0046] This ensures that an optimal length of the support member is achieved. On the one hand, the length should not be too large, as this would have an adverse effect on the waste of material. On the other hand, the length should not be too small, as this would impair the beneficial support effect of the female terminal on the surface of the outer shell. Therefore, the inventors have found that an optimal balance should be achieved according to the values proposed here.
[0047] In a preferred embodiment of the electrical connection system, the first extension portion intersects the second extension portion at the bend portion, and the intersection angle is at least 60°, preferably at least 70°, preferably at least 80°, preferably at least 85°, and / or the intersection angle is at most 120°, preferably at most 110°, preferably at most 100°, preferably at most 95°, and most preferably the intersection angle is about 90°.
[0048] In a preferred embodiment of the electrical connection system, the surface is a top surface arranged on an end of the housing opposite to the receiving portion and is substantially parallel to the mating direction.
[0049] In a preferred embodiment of the electrical connection system, the portion of the female terminal surrounded by the bent portion is at least 1 times, preferably at least 2 times, preferably at least 3 times, preferably at least 4 times, preferably at least 6 times, preferably at least 8 times, preferably at least 10 times, and / or is at most 20 times, preferably at most 16 times, preferably at most 14 times, preferably at most 12 times, preferably at most 10 times, the bending radius of the intersection of the extension section of the first extension section and the extension section of the second extension section.
[0050] As described elsewhere herein, the curved portion of the female terminal may not be limited to a mathematical point or edge where the extensions of each of the first elongated portion and the second elongated portion intersect.
[0051] In a preferred embodiment of the electrical connection system, the bent portion has two supporting members, which are arranged basically symmetrically on opposite sides of the bent portion, wherein the surface of the shell is provided with two corresponding recesses, which are arranged basically symmetrically on opposite sides of the bent portion so as to at least partially accommodate the two supporting members.
[0052] Preferably, the at least one support member projects substantially perpendicularly from the second elongate portion.
[0053] Preferably, the housing comprises at least one opening, to which the at least one female connector is led, wherein the receiving portion is arranged substantially centrally in the opening as seen in the mating direction.
[0054] Preferably, the electrical connection system also includes a second female terminal, which is arranged on a plane substantially parallel to the first female terminal, wherein the system preferably includes at least one shielding element, which has a through hole for receiving at least one female terminal, and the shielding element is used to be received in the hollow part of the shell, wherein the system preferably includes a cover arranged on the top of the surface of the shell, for at least partially covering the shell and the at least one female terminal, wherein the system preferably includes at least one wire, which is connected to the second extension part at an end portion of the second extension part opposite to the bending portion of the female terminal, wherein the system preferably includes an overmold, which is arranged on the top of the cover, and the overmold is configured to at least partially accommodate the cover and the at least one wire, wherein the system preferably includes a sealing element arranged between the overmold and the shell.
[0055] On the other hand, a method for assembling an electrical connection system is provided, the method comprising the following steps: providing an electrical connection system according to any embodiment of the aforementioned aspects; optionally setting a sealing element between the overmolding and the shell; optionally connecting at least one wire to the second extension portion at an end portion of the second extension portion opposite to the bent portion of the female terminal; setting a cover on the top of the surface of the shell for at least partially covering the shell and at least one female terminal; and setting an overmolding on the top of the cover, the overmolding being configured to at least partially accommodate the cover and at least one wire.
[0056] The method includes all the advantages of the electrical connection system described herein. In particular, it should be noted that the method described herein may include all aspects and / or embodiments described herein, even if not explicitly described as a method, but with reference to an electrical connection system. It should also be understood that the features and advantages described with reference to the electrical connection system are equally applicable to the method described herein.

[0068] The term "and / or" only describes the association relationship of associated objects, and indicates that there may be three relationships. For example, A and / or B may represent three states: that is, A exists independently, A and B both exist, and B exists independently. In addition, the character " / " in the present disclosure generally indicates that the preceding associated object and the succeeding associated object form an "or" relationship.
[0069] In the following paragraphs, the present invention is described in more detail with reference to the accompanying drawings. It should be noted that other embodiments are of course possible, and the following explanation is provided by way of example only and not by way of limitation. In the drawings and the specification, the same reference numerals refer to the same elements. The drawings may not be drawn to scale, and the relative sizes, proportions, and descriptions of the elements in the drawings may be exaggerated for clarity, illustration, and convenience.
[0070] Fig. 1, Fig. 2a, Fig. 2b and Fig. 2c show an electrical connection system 1 according to the prior art. Some features can also be used to understand the electrical connection system 1 of the present invention in more detail. In addition, some features can also be compatible with the electrical connection system 1 of the present invention. Fig. 1 is an exploded view and shows an outer shell 20, a sealing element 70, two shielding elements 30, two female terminals 10, two wires 60 respectively connected to each of the two female terminals 10, a cover 40 and an overmolding 50. Fig. 2a shows a female connector 2, a bent portion 11, a receiving portion, a cavity 21 in an outer shell 21, and an opening 22. Fig. 2b shows a mating state with a male terminal 65. The connection system 1 of the prior art shows that the female terminal 10 is not correctly positioned. The female terminal 10 is tilted and not parallel to the mating direction MD. In particular, the tulips are not in their correct position (as best shown in Fig. 2c).
[0071] Figure 3 , Figure 4 and Figure 5 An electrical connection system 1 according to an embodiment of the present disclosure is shown. As shown, the bent portion 11 of the female terminal 10 has at least one support member 13 for supporting the female terminal 10 on the surface 23 of the outer housing 20 so that the female terminal 10 is substantially prevented from moving in the outer housing 20.
[0072] The at least one female terminal 10 ( Figure 3 , Figure 4 and Figure 5 Two are shown in the figure) including a first elongated portion 15 oriented substantially parallel to the mating direction MD and at least partially received in the hollow portion of the shell 20, and a second elongated portion 16 oriented in a direction different from the mating direction MD. The hollow portion may include a portion of the cavity 21. The bent portion 13 is arranged between the first elongated portion 15 and the second elongated portion 16. The support member 13 is arranged so that the free edge of the support member 13 contacts the surface 23 of the outer shell 20. In particular, the free edge abuts the surface 23 along its length in the direction of the second elongated portion 16. The support member 13 is bent in the mating direction MD and extends from the second elongated portion 16. As can be seen in Figure 7 As best shown in FIG. 1 , the support members 13 , 13 ′ have a wing shape.
[0073] like Figure 3 and Figure 4 As best shown in FIG. 2 , the surface 23 of the outer shell 20 is provided with corresponding recesses for each of the support members 13 , 13 ′ so as to at least partially accommodate them.
[0074] like Figure 5 As best shown in FIG. 1 , each of the support members 13, 13' includes a slit 17 (only one is indicated for the sake of brevity) on an edge facing the second elongate portion 16. The slit 17 extends along the elongate direction of the second elongate portion 16. The slit 17 extends from the first elongate portion 15 (eg, Figure 3 and Figure 4 The longitudinal direction of the longitudinal axis of the second elongated portion 16 is shown in FIG. 1 , and starts from the intersection of the longitudinal axis of the second elongated portion 16 and extends in a direction along the second elongated portion 16.
[0075] The first elongated portion 15 and the second elongated portion 16 intersect in a curved portion 11 with a curvature radius 18 (as indicated in prior art FIG. 2b ) as described elsewhere herein. The width w and length l of the support members 13, 13' are Figure 8 The first elongated portion 15 and the second elongated portion 16 may intersect at the curved portion 11 at an angle of approximately 90°.
[0076] The surface 23 is a top surface disposed on an end portion of the outer housing 20 opposite to the receiving portion 12 and is substantially parallel to the mating direction MD.
[0077] As indicated in all figures, the curved portion 11 encompasses a portion greater than the mathematical point or edge at which the extensions of each of the first elongate portion 15 and the second elongate portion 16 intersect.
[0078] like Figure 3 and Figure 4 As best shown, the receiving portion 12 can be arranged substantially centrally in the opening 22 as viewed along the mating direction MD. The receiving portion 12 of the female terminal 10 can be spaced apart from the opening 22 by a predefined distance. The support member 13 can be configured to maintain a predefined distance between the second elongated portion 16 and the surface 23 of the outer housing 20. Figure 3 and Figure 4 As best shown, an annular gap is formed between the first elongated portion 15 and the hollow portion of the outer housing 20. The annular gap may be substantially uniform along its periphery. These improvements cannot be achieved by the electrical connection system 1 of the prior art (FIGS. 1, 2a, 2b and 2c).
[0079] The preferred wire 60 used in the electrical connection system 1 of the present disclosure may have a diameter of 0.2 mm. 2to 0.8 mm, preferably 0.3 mm 2 to 0.6 mm, preferably 0.35 mm 2 To 0.5mm size.
[0080] Figure 6 , Figure 7 and Figure 8 Different steps of a manufacturing process of the female terminal 10 according to an embodiment of the present disclosure are shown.
[0081] As shown in the figure, the supporting members 13, 13' (for the sake of simplicity, Figure 6 The female terminal 10 and the supporting members 13, 13' are formed as a single piece with the female terminal 10. The female terminal 10 and the supporting members 13, 13' are made of stamped and bent metal plates. Figure 6 As best shown, a portion A is cut away between each female terminal 10. This allows the support members 13, 13' to take on a wing shape. Figure 7 Compared to Figure 8 It is shown that the female terminal 10 is bent to approximately 90°.
